simulated_confidence_intervals_of_mean: Create simulated confidence intervals

In michaelfrancenelson/mfn.teaching.utils:

Create simulated confidence intervals

Description

Simulation of Frequentist confidence intervals of the mean of normally-distributed data.

Usage

simulated_confidence_intervals_of_mean(
  n_samples,
  n_intervals = 1,
  alpha = 0.05,
  pop_mean = 0,
  pop_sd = 1
)

Arguments

n_samples	The sample size for the confidence intervals.
n_intervals	The number of intervals to generate.
alpha	Confidence level
pop_mean	Population
pop_sd	population standard deviation

Examples

require(ggplot2)
ggplot(
  simulated_confidence_intervals_of_mean(n_samples = 20, n_intervals = 20),
  aes(x = simulation, colour = in_sample_ci)) +
geom_point(aes(y = sample_mean)) +
geom_segment(aes(xend = simulation, y = lower_t, yend = upper_t)) +
  geom_hline(yintercept = 0, lty = 2)
